I've seen a few e-ereaders out there while at the doctors office, even at court. Within the first 2 days that the Kobo was released they were sold out all over Burlington. Then again were sold out after the release of the black coloured ones. Also, my boss has a Sony, my co-worker has a Kobo wi-fi and she's getting a Touch (she won it from Kobo).
I have the original Kobo (which my sons use) and I take my Kindle everywhere I go.
I don't like to judge the popularity of an item by what I see in the street. I'm sure a lot of people just like reading at home
